Basic knowledge of R.

.RData is an R file that contains data sets. You can read these data sets using load("~/filename/name.Rdata").

It is better to put the file that contains name.RData under the default R working directory which can be denoted as ~.

To get the default working directory of R/RStudio

> getwd()

[1] “C:/Users/Administrator/Documents”

Set working directory

> setwd('~/Dropbox/ARIC/PHENOTYPES/output')

Load datasets

> load("~/Dropbox/ARIC/PHENOTYPES/data/ARIC.RData")

The reason for choosing dropbox as sub-directory is that different people can run and edit code, as well as make outputs under “sharing folder” mode.
